There’s nothing wrong with pulling used engines from Ferraris, except the price. With an F136 you get a 4.5-liter 570-horsepower V8 mill that’s won International Engine of the Year eight times, and it’s wildly dependable as long as it’s maintained.

One thing used engines from Subarus were practically made to do is power Volkswagens. Beetles, Westphalias, buses, Transporter trucks, even Synchros can adapt 2.5 Subaru used engines with ease. The original mills had well under half the power of even a stock EJ, and most people report an increase in gas mileage as well. Subaru reliability, classic Volkswagen style, what’s not to love?

This new take on the Mustang was good for 310 hp and 300 lb-ft of torque, could do 0-60 in 5.9 seconds, and top out around 152 in its heyday. Of course, these models are a bit dated by now, but if you can find one in good condition (which our research estimates will run you about $8,000), one of these crazy cheap cars will surely still bring a smile to your face.

That’s why builders of the 240sx, FD RX7, and all kinds of custom applications have used engines from the LS family they’re all durable, well-built, and cheap to modify.
